The
fact of the matter is that almost 90% of older British sports cars are
in desperate need of floor and sill replacement. Anyone with the desire
can take a few classes at a local vocational school and learn to weld
in a short time. With the rising costs at restoration and body shops
you can do the work yourself with a little practice and save money to
use on another restoration! For about $200 - $250 a simple welding
outfit can be purchased. However most clubs use funds to buy equipment
like this so before you go out and buy your own check out your local
club and see what resources they already have.
At
this stage most of our cars have holes or rust developing in the floors
and rocker panels. It s very important with a unitized chassis that the
bottom of the car Is completely sound because of the lack of support
from lack of a roof. Over time as the floor and sills deteriorate you
will notice the door gaps have changed and don t close as easily as
they did while new. This is evidence of a weak floor and sills that
need to be retired. Moss supplied me with the high quality reproduction
parts I needed. For most of us this is a hard part, so take your time
and be sure to buy all the correct parts to replace anything that shows
any sign of deterioration . Also, don't overlook replacement of the
door hinges and footwell panels. The most effective plan of action is
to work on one side of the car at a time, removing and carefully
replacing the required panels using the untouched side as a source of reference.
Continue
by removing the old rocker panels and the cross-member. After cleaning
up the rusty edges all around the base of the car, then and only then,
can you install the new floor-pan. Offer up the new floor into place
and temporarily support it with five or six jack stands. Start by
lining up the floor edge against the rear bulkhead; the front can be
trimmed later. Tack weld the rear edge to the bulkhead in front of the
rear axle under the car. Before welding the front of the floor-pan and
footwell sides, the door gaps must be checked again and again. It is
impossible to stress how important this step is.
Lightly
tack weld or rivet replacement panels in place until everything is
together; make adjustments to align doors, etc. (you will make
adjustments) and then seam-weld together for strength. The best way to
do this is to lay all the parts on a level surface and test fit them
together. Start by tack welding the inner rocker panels to the outer
panels. Measure carefully and line up the jacking holes properly, then
weld the cross-member to the floor, along with the footwell panels (if
you plan on replacing them, too). After assembling the floor parts
together, use a good rust preventative (We sell the best! A 2 1/2 liter
kit of Finnigan's Waxoyl is sold under #225-360 - Ed) inside the cross-member and rocker panels.
The
process of removing old panels is, in some regards, even more important
than their replacement. Take careful note of how it all fits together
and duplicate that as accurately as possible. Be careful not to destroy
pieces you will need to reweld. Patience here goes a very long way.
